Sydney Sweeney wowed Hollywood on October 25, 2025, at the AFI Fest premiere of her new biopic “Christy.” She looked amazing and turned heads on the red carpet. The actress wore a custom pastel pink Miu Miu dress with delicate floral lace and a belted drop-waist shape that went perfectly with her new, icy blonde bob haircut. Sweeney made a big change in her style, which was a big step for her. She also changed her body for her role as boxing legend Christy Martin.
Changes in Hair and Style
Glen Coco, Sydney’s longtime hairstylist, used Kérastase products to give her a chic, wavy blonde bob. The look was inspired by old Hollywood and had a glossy finish. The icy blonde color really brought out her eyes and framed her face. It was a great contrast to the softness of her Miu Miu gown. Makeup artist Melissa Hernandez used Armani Beauty to give the look a natural, glowing look. She used rosy colors on the cheeks and eyes to match the pink tones of the dress.
Changing Your Body for the “Christy” Role
Sweeney gained about 30 pounds and spent a lot of time learning boxing techniques to make her portrayal of Christy Martin, the first female boxer, more realistic. She said the experience gave her strength and power, and she threw herself into the role to show Martin’s strength and resilience on screen. David Michôd directed the movie, which will be released in theaters across the country on November 7, 2025.
A Star-Studded Premiere and Accessories
Christy Martin, a boxing legend, was at the premiere at the TCL Chinese Theatre. She walked the red carpet with Sweeney. Sydney added beautiful jewelry from Kallati and Le Vian to her outfit. The jewelry included a $23,190 14k rose gold sapphire ring and delicate rose quartz earrings that made her look even more elegant.
